[. . . ] Bolo Tine Kit OEM-290-253 / 290-253-081 for HORSE TM, ECONO HORSE TM, and PONY ® Tillers Installation Instructions THANK YOU! Thanks for buying new bolo tines. These tines were designed for your model tiller and will handle all of your tilling needs including sod busting, seedbed preparation, cultivating, and turning under crop residue. How To Use These Instructions These instructions apply only to owners of the following tillers: ❒ HORSETM Model ❒ ECONO HORSETM Model ❒ PONY® Model First, read the general information given for all model tillers on Pages 1 through 4. You will then be directed to installation instructions for your particular model tiller. Carefully look at the adjacent figures while following the step-by-step instructions. [. . . ] Position the box (with the attached template) in front of you as was done when assembling the "A" gangs. Place two right-curved tines (shown in Figure 17 on Page 10) onto the template so that the tines cover outlines of tines #3 and #4. Place two left-curved tines (shown in Figure 18) onto the bolts so that the tines cover the outlines of tines #1 and #2. These tines are opposite each other on top of the tines already in place. The tips of these tines point downward (overhanging the sides of the box). @ ; @ ; @ ; ;; #3 BOLT ER BOLT AL EL or ER or AR EL AR or #4 ;; AL E TIN #4 INTS PO UP or BOLT TINE POINTS DOWN #2 9 Cutting Edge E TIN #3 INTS UP PO #3 BOLT ER or TINE POINTS DOWN #1 BOLT AL EL or Cutting Edge TINE POINTS DOWN #1 AR ER or AR EL or BOLT #4 ;; AL E TIN #4 INTS PO UP TINE POINTS DOWN #2 #4 Cutting Edge Figure 17: Assembly of a "B" gang.

Add locknuts to the three bolts and barely tighten the nuts (just so they do not fall off the bolts). Step 4: Install Gangs on Holders In the gangs just assembled, all cutting edges are facing in one direction. When installed on the holders, these cutting edges must enter the soil first when the tiller is moving forward. Figure 19 shows the correct position on the tine holders for the three "A" gangs and the "B" gang. Note that each holder shows a letter which corresponds to the "A" and "B" markings on the tine gangs just assembled, and a number which represents the order in which the tine gangs are installed on the holders. Take one "A" gang and wrap it around the tine holder at position #1. Check that the cutting edges are positioned so that they will enter the soil first when the tiller moves forward. 10 B. Rotate the gang so that the the two innermost tines are around one lug on the tine holder and the other two tines are around the other lug.

Rotate HORSE and ECONO HORSE Tines for Longer Tine Life HORSE and ECONO HORSE bolo tines can be rotated to obtain a longer life. PONY tines are subject to equal wear because the tine pattern is the same for all tines on a holder. Therefore, rotating tines is not effective for that model. ❑ Rotate tines once during their life cycle to increase tine life up to Inspect Tines for Wear Inspect tines after the first 10 to 15 hours of tiller operation and then after every 10 hours.
